Swift Performance Premium

Slow pages frustrate visitors, and fixing them by hand often means juggling separate tools for caching, scripts, styles and images. This plugin gathers those jobs in one place. It analyzes how your site loads resources and adjusts loading for real visitors, with automatic configuration that spares you most of the manual setup.

It works on the common speed measures: Largest Contentful Paint, First Input Delay, Cumulative Layout Shift, First Contentful Paint, Interaction to Next Paint and Time to First Byte. It covers mobile and desktop, and its JavaScript handling reaches logged-in and non-cacheable pages. Blogs, business sites and agency client projects can all use it.

Features

• Automatic speed tuning: The plugin analyzes how your site loads resources for real users and adjusts them automatically, so you can get started without a long manual setup.
• Asset preloading: Critical images, fonts and other assets are preloaded to help the main content appear sooner on both mobile and desktop devices.
• JavaScript execution handling: JavaScript parsing and execution are managed to reduce input delay, including on logged-in and non-cacheable pages where quicker interactions matter.
• Layout shift reduction: CSS, JavaScript and fonts are optimized for real-world use to prevent unexpected layout shifts and keep the page visually stable while it loads.
• Critical CSS generation: The plugin generates critical CSS and preloads essential resources so the first content paints sooner, including on slow mobile connections.
• Interaction responsiveness: Interaction to Next Paint optimization keeps the page responding smoothly after the initial load has finished.
• Caching and server response: Preloading, smart caching and support for third-party tools work together to help pages respond quickly from the first server response.
• Automated image optimization: Images are optimized automatically, balancing visual quality against file size so pages load faster.
